use .kv:
$ 6 'my @a = <a b c>; for @a.kv -> $index,$value { dd $index, $value }'
Int $index = 0
Str $value = "a"
Int $index = 1
Str $value = "b"
Int $index = 2
Str $value = “c"
Mind you, you can actually chain that with your sort:
$ 6 'my @a = <c b a>; for @a.sort.kv -> $index,$value { dd $index, $value }'
Int $index = 0
Str $value = "a"
Int $index = 1
Str $value = "b"
Int $index = 2
Str $value = “c"
